FUEL-ECONOMIZING APPARATUS.

Application filed November 6, 1922.

T 0 all whom t may concern:

Be it known that I, THoMAs BoccHINo, a citizen of the United States, and resident of Poughkeepsie, in the county of Dutchess and State of New York, have invented certain new and useful Improvements in Fuel-Economizino* Apparatus, of which the following is a specification.

My invention relates to fuel economizing apparatus for use in Aconnection with furnaces, and my improvements consist more particularly in a novel arrangement of smoke pipes and dampers in combination with a source of vapor supply whereby to prevent the escape of combustible gases from and assure burning of the same within a furnace.

With the foregoing general purpose in view, my invention consists in the novel features of construction, combination and arrangement of parts to be hereinafter more fully described, illustrated in the accompanying drawings and particularly defined in the appended claims.

In the drawings wherein like characters of reference denote corresponding parts in the separate views,

Figure 1 is a vertical section of a fuel economizing apparatus including the novel and essential features of my invention; and

Figure 2, 'a section on the line 22 of Fig. 1.

Referring to the drawings in detail, 10 designates a smoke pipe of suitable length that has extending therefrom and communieating therewith a branch pipe 11, which latter is of limited length and has its outer open end slidably engaged with a vapor head 12 that is disposed within a water pan 13.

The branch pipe 11 extends at right angles or substantially at right angles to the pipe 10 from a point in the latter intermediate its inlet and outlet end portions 14 and 15, respectively, and is divided by a central, longitudinal partition 16 that is disposed at right angles to and terminates within the pipe 10 at 0r near the center thereof as shown. The partition 16 forms within the pipe 11 a pair of passages 17 and 18, both of which, at the outer end of the pipe, open into the vapor head 12, and at the other or inner end of said pipe, open, respectively, into the inlet and outlet portions thereof, which inlet and outlet portions are adapted to be connected, respectively, with Serial Nfo. 599,356.

a furnace and a stack or chimney, as is understood.

Disposed within the pipe 10 adjacent to the inner end of the partition 16, so as to be operable to form a continuation of the latter to completely or'partially close said pipe as may be desired, is a damper 19, while within the outlet portion 15 thereof is another damper 20. From this arrangement it is obvious that when the damper 19 is opened direct communication between the inlet and outlet ends of pipe 10 is permitted and that when said damper is closed such direct communication is denied and communication then established between the inlet and outlet ends of the pipe 10 by way of the passages 17 and 18 and the vapor head 12.

The vapor head 12 preferably is of circular shape and somewhat larger in diameter than the pipe 1l and includes a reduced neck portion 21 within which the outer or lower open end of said pipe is snugly and slidably fitted. rlhis vapor head is adapted to contain water and any desired means may be employed to maintain the water at a predetermined level therein. I prefer, however, they arrangement shown consisting of the pan 13 having a water supply pipe 22 connected therewith that is equipped with a oat controlled valve 23. This valve operates in a well known manner to maintain the water at a fixed level within the pan, and since the vapor head is seated in the pan and provided with openings such as are shown at 24', it is apparent that the same level of water as exists within the pan'also exists within the vapor head.

In using my improved apparatus, bothv dampers 19 and'20vinitially are opened to provide a direct draft through pipe 10 and they are maintained open until the lire in the furnace has burned up brightly and substantially all of the smoke has disappeared, Damper 19 then is closed to deliect the hot gases from the furnace through the passage 17 and into the vapor head 12. The hot gases, coming into Contact with the water within the vapor head, vaporize the water and the vapor thus produced rises and fills the pipe 11. Damper 20 then is regulated to secure sufficient draft from the furnace to the chimney or stack by the indirect way of passages 17 and 18 to maintain the fire burning at a desired temperature. rIhe vapor within the pipe 11, however, acts as a check to the passage of unburnt combustible gases from the furnace to the chimney and consequently such gases are retained within the furnace and consumed with a resultant saving in the consumption of fuel as is apparent.

I claim l. Fuel economizing` apparatus comprising a pipe adapted to be connected at one end with a furnace and at its other end with a chimney, a water container, aid pipe having` a pair of passages leading therefrom and terminating in said water container, and an adjustable damper within said pipe between said passages operable in one position to restrict communication bctween the furnace and chimney through said passages and sinniltaneously permit direct comn'iunication between the furnace and chimney through said pipe and in another position to deny such direct communi.- cation and necessitate communication between the furnace and chimney by way of said passages and said water container.

2. Fuel economizing` apparatus comprising a pair of connected pipes, one of which is adapted to be connected at its respective ends with a furnace and a chimney, a partition within the other pipe dividing' the same into a pair of passages, a water container within which the outer end of said second mentioned pipe is disposed, and an adjustable damper within said first pipe operable in one position to restrict communication between the furnace and chimney through said passages and simultaneously establish direct communication between the 'furnace and chimney through said iirst pipe, and in another position to form a continuation of said partition and interrupt such direct communication. l

3. Fuel economizingr apparatus comprisingry a pipe adapted to be connected at one end with a furnace and at its other end with ya chimney, a water container, means to maintain water at a constant level within said container, said pipe having a pair of passages leading` therefrom and terminating in said water container, and an adjustable damper within said pipe between said passages operable in one position to restrict communication between the furnace and chimney through said passages and simultaneously establish direct communication between the furnace and chimney through said pipe and in another position to deny such direct communication and necessitate communication between the furnace and chimney by way of said passages and said water container.

1. Fuel economizing apparatus comprising;v a pair of connected pipes, one of which is adapted to be connected at its respectiveends with a furnace and a chimney, a partition within the other pipe dividing the same into a pair of passages, said partition extending' into said rst mentioned pipe and terminating` substantially centrally thereof, a water container within which the outer end of said second pipe is disposed, and an adjustable damper operable in one position to restrict communication between the furnace and chimney through said passages and simultaneously establish direct communication through said first pipe, and in another position to form a continuation of said partition and interrupt such direct communication. i

Fuel economizing,` apparatus comprisiup; a pipe adapted to be connected at one end with a furnace and at its otherend with a chimney, a vapor head, a branch pipe leading from said iirst pipe and being slidably connected with said vapor head, a water pan within which said vapor head is disposed, means establishingcommunication between said vapor head and said water pan,'means to maintain water within said pan at a constant level, a partit-ion within said branch pipe dividing the same into a pair of passages, an adjustable damper within said first pipe operable in one position to permit direct communication therethrough and, in another position to deny such direct communication and necessitate communication between the furnace and chimney by way of said passages and saidA vapor hea-d, and another adjustable damper within said first pipe between its last mentioned end and said first damper.
